1 Claim. (Cl. 21938) This invention relates to portable electric vabodyand which is in circuit, through said sleeve porizers and has for itsprincipal objects the 2| and the usual bottom contact screw (notDIOViSiOn O a Simple, cheap and eflicient conshown), with the terminalsiii of said socket struction which is compact, of attractiveappearmember I2. A disc 24 of mica or like insulation 5 ance and safe tohandle when in operation. is interposed between said coil and the topflange 5 Other objects of the invention are hereinafter 25 of the shell22. Said disc is preferably perset forth, forated to admit of thepassage of heated air In the accompanying drawing in which I havecurrents from said coil directly to the bottom illustrated a preferredembodiment of my inof the receptacle. vention A metal deflector or hoodmember 30, of a 10 Figure 1 is a vertical section, partly inelevagenerally truncated cone-like configuration and tion, d having acircular top 3i is adapted to be sup- Fig. 2 is a plan view, partlybroken away. ported by e flange 25 of s Shell Referring to the drawingand the construction A receptacle 32 for volatile liquid has thebotshown therein the reference numeral desigtom 33 thereof Welded, orotherwise secured, to 16 nates a hollow base member preferably formedthe top 3| of the deflector 30. of sheet metal, the same beingcontracted at To operate the vaporizer, when assembled and its upper endto form a heat-radiating deflector plugged into an electric circuit, theliquid such member 2.

The socket Due o the disposition of theheat-radiating 40 has the 115113,} terminals I5 (only one beingdeflectors With respect to the heating element shown), to which aresecured in the well known and the liquid receptacle, it is possible 0 emanner the circuit leads in one of which is interfeetilely utilize theheat from the heating posed a switch l5 and which leads extend mentwithout danger of the vaporizer becoming through a tubular cord orcovering H to a knife too hot to handle when shifting the position of 45or blade plug l8. the vaporizer to a different location in the same Aresistance heater element or plug, also of or a diiferent room or toresult in the vaporizer standard construction, such as the type used inbecoming a fire hazard even should the same not electric cigar lighters,is mounted in the socket be equipped with a thermostatic cut-off switchI3. Said element comprises a body 253 of refracor time switch, 50 toryheat-insulating material having a threaded The construction of myvaporizer is extremely metal sleeve 2|, a protective metal shell22,1atsimple and owing to the fact that it utilizes erally surroundingthe upper portion of the body standard electric plugs and sockets, anypart that 20, and a coil 23 of resistance wire, mounted in becomes wornout can be readily procured and a flat spiral groove formed on the topof said replaced without necessitating the return of the 55 device tothe manufacturers or to a repairshop.

Various changes from the preferred construction herein illustrated maybe made without departing from the spirit of my invention as embracedwithin the scope of the appended claim.

Having thus described my invention, what I claim and desire to obtain byUnited States Let'- ters Patent is:

In an electric vaporizer, the combination comprising a base memberhaving a heat-deflecting shield at its upper end and a transverse,centrally perforated intermediate partition of insulation material, athreaded sleeve mounted in said partition, a-frame carried by saidsleeve, a lock nut for rigidly securing said sleeve to said partition,

an electric socket mounted on saidframe, an insulation sleeve envelopingsaid socket, supporting means carried by said frame arranged to engagethe bottom of said sleeve when the same is positioned on said socket, aresistance heatingelement removably mounted in said socket, a metalreceptacle mounted on said resistance heating element, said receptaclehaving a flared, heat-deflecting shield depending therefrom, an electriccircuit interconnecting said heating element and said socket when thetwo are in cooperative engagement and means for connecting said circuitto a source of electricity.
